Anatomy & Physiology: Muscles—Flexor Hallucis Brevis.
Structure.
- Origin: cuboid and 1/3 lateral cuneiform.
- Insertion: medial and lateral sides of proximal phalanx of great toe via a tendon containing a sesamoid bone.
Function.
- Concentric action: flexion of great toe at metatarsophalangeal joint.
- Reverse mover action: flex metatarsal of hallux at MTP.
- Eccentric action: control/restrains/decelerate extension of MTP of hallux.
- Isometric action: stabilization of MTP of hallux.
- Innervation: medial plantar nerve.
